Physical layer security (PLS) is an approach in the field of information security that focuses on securing wireless communication at the primary physical layer, rather than relying solely on higher-layer encryption and cryptographic methods. PLS leverages the inherent characteristics of the physical layer of communication systems to protect data from eavesdropping and other security threats. In this paper, we examine the PLS for the correlated Nakagami-m fading medium. The arithmetical statements for the secrecy outage probability (SOP) as well as the ergodic secrecy capacity (ESC) have been derived. Based on the outcomes of the mathematical statements, the secrecy performance is analysed for the legitimate user. As the fading parameter of the legitimate user is hiked the SOP decreases and ESC increases. It is also discerned that as the average SNR of the legitimate receiver increases, the SOP decreases and the ESC increases for the correlated Nakagami-m fading channel.
